School of Engineering, G.D.Goenka University organised an educational trip to Nanoscale Research Facility at Indian Institute of Technology, New Delhi on 2nd March, 2016. A group of 38 students of B. Tech 1st year and faculty members, Dr. Sandeep Nagar and Dr. Mayurika Goel from School of Engineering visited the facility.
Nanoscale Research Facility is one of its kind equipped with the flexibility to provide requirements according to the specific projects due to its multi-disciplinary nature. The facility was started with the objective of designing and building nanoscale structures and devices. Targeted Deliverables are nanophotonics, nano electronics, nanomechanics, nano photovoltaics and biosensors. Firstly Dr. Raman Kapoor,Senior Scientific Officer introduced the rationale behind the requirement of astate of the art research facility, thereafter students were divided into three groups for the Photo catalysis lab, Chemistry lab, and the nano material Characterization lab.
In the chemistry lab, students were introduced with the primary instrument required to determine the size and the stability of nanoparticles: Particle Size Analyser(DLS). The students were told about the importance of separation techniques with set of advanced chromatographic instruments. High performance Liquid Chromatography (HPLC) and Gas Chromatography coupled with Mass Spectrometer are used to separate complex mixtures on the basis of retention factor on the stationary phase. In Photo-catalysis lab, students got to know about the splitting of water for exploring greener fuels with a photo-electrochemical work station to determine the catalytic activity and a fuel cell test system.
Among another hyphenated instruments were a four probe station used to acquire signals from the internal nodes of a semiconductor device. The probe station can work with extreme temperature variations. One of the researcher, Mr. Ausotosh elaborated the magnificent work in the area of carbon nano rods, wires and Quantum dots and how the size at nanoscale drastically changes the properties of materials. Common lab facility was equipped with an Atomic Force Microscope which can analyse the surface of a rigid material all the way down to the level of the atom. It magnifies the surface significantly and produces the 3D image of the surface. Lastly, an ultra-resolution Nanofabrication facility with a high end Electron Beam Lithography instrument, Photo-lithographer coupled with a scanning electron microscope (Class 1000 Clean room) and Wafer Bonding/Packaging, was explained by Dr. Kapoor.
This visit was to enhance the knowledge of various modules of the Nanotechnology group students. The interaction with the researchers also enlightens the students about the new concepts and fundamentals for nanoscale processes. It was indeed auseful experience satisfying the curiosity of engineering students.
